POLISHING-WHEEL.

SPECIFICATION forming part of Letters Patent No. 234,367, dated November 9, 1880,

Application filed August 16, 1880.

To all whom it may concern.-

Be it known that I, XAVIER YAHLE, of

.Newark, in the county of Essex and State of of which the following is a specification.

My invention relates to an improvement in buffing or polishing wheels, securing them against the liability of bursting; and it consists in the method of uniting the pieces for the wheel, and in the use of flange-plates binding them together.

Figure 1 is a plan view of one side with the flange-plate removed. Fig. 2 is a cross-sec' tion, showing the plates in position. Fig. 3 is an inverted plan of one of the plates.

I construct my wheels of pieces of wood A- twenty, more or lesshaving the grain concentric with the center of the wheel, and these are firmly glued together. In the face, on one or both sidesusually b0tha few inches from the center, I form a circular recess, B, for the reception of the flange O, projected from the surface of the plate D. These plates will usually be let in flush with the sides of the wheel, as seen in Fig. 2, but they may be put on the outside, and are united together by the bolts E.

One of the plates has a bearing-center, F,

(No model.)

extending through the wheel and through the opposite plate; or, in place of the bolts, the part F may be screw-threaded, and the plate it passes into be fitted to screw onto it and lock them together.

The plates may be made with two or more flanges, if found desirable, and recesses formed to receive them; but usually one will be found to be sufficient, and in place of circular flanges they may be made angular and accomplish the same purpose, the invention being in the flange on the inside of the plate made to enter a recess in the side of the wheel to prevent the parts of the Wheel flying apart. These Wheels are much stronger and will not warp or shrink out of shape.

What I claim as my invention, and desire to secure by Letters Patent, is-

The buffing 0r polishing wheel made with strips of wood having the grain concentric -with the center, and having the recess B, in

combination with the plate D, provided with the flange O, and one of said plates forming the center bearing, F, substantially as and for the purposes specified.
